The prize-winning essays during this booklet deal with the attention-grabbing yet occasionally uncomfortable courting among physics and arithmetic. Is arithmetic in simple terms one other common technology? Or is it the results of human creativity? Does physics easily put on arithmetic like a dressing up, or is math the lifeblood of actual truth?

The current quantity is a compilation of the talks offered on the 1972 Coral Gables convention on primary Interactions at excessive power held on the college of Miami by means of the guts for Theoretical stories. the amount includes, furthermore, contributions via B. Kursunoglu and G. Breit, which have been now not truly provided, yet are incorporated as tributes to Professor P.

The Rock Physics guide very easily brings jointly the theoretical and empirical family members that shape the rules of rock physics, with specific emphasis on seismic homes. it's also generic versions and kinfolk for electric and dielectric rock homes. Seventy-six articles concisely summarize quite a lot of issues, together with wave propagation, AVO-AVOZ, potent media, poroelasticity, pore fluid stream and diffusion.

Here we enhance interactions between the mf = −9/2, −5/2 spin states using a Feshbach resonance between these states at ∼224 G. At the position of the Feshbach resonance where σ is large, the aspect ratio σz /σy decreases. As the gas becomes collisionless away from the resonance the aspect ratio smoothly evolves to the collisionless value. The key to observing anisotropic expansion in these systems is that during the beginning of the expansion the magnetic field must remain at the value near the Feshbach resonance.

Figure 8 shows how a diverges according to Eq. (6) for the 40 K resonance described in the next section. 2. A S PECIFIC E XAMPLE To further illustrate Feshbach resonance physics it is useful to consider a specific atomic example. Here we will discuss the case of the 40 K resonance that is used for most of our BCS-BEC crossover studies. A. S. Jin [3 F IG . 8. Behavior of the scattering length at a Feshbach resonance in 40 K between the mf = −7/2, −9/2 spin states. F IG . 9. 40 K ground state level diagram, with exaggerated Zeeman splittings.
